As with capital goods (tangible items such as buildings, machinery, and equipment produced and used in the production of other goods and services), the consumption of a durable good is spread over its life span, which tends to create demand for a series of maintenance services.
The event which is referred to as The Phoenix Lights comprised of a series of incidents, involving a number of different craft and orbs which took place during the evening of March 13th 1997.
Video of the Phoenix Lights appeared on TV tabloid shows with breathless commentators wondering if this was the proof UFO believers had been waiting for. And when Gov. Fife Symington called a press conference, few expected to see the extraterrestrial who emerged from backstage (a Symington aide in alien drag).
